Why do scientists use Latin for the scientific names of organisms

Scientist use Latin language for naming and classification because it is an ancient language and is not spoken in any region of the world also doing this reduces the chance of conflict between countries over using their native languages as base of classification which would be very unhealthy for a growing scientific environment.

Key scientific figures such as Newton and Mendeleev published their papers and findings in Latin. When Swedish scientist Carl Linnaeus started to devise a system of classifying organisms, he gave different phyla and species Latin names, because Latin was such a universal scholarly language in Europe.
